(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC Resistance is measured with a Digital Multimeter TR6871
(Advantest) or equivalent.
(3) Maximum allowable DC current is that which inductance decrease
current, or temperature rise current, whichever is smaller.
・ Inductance decrease current : The inductance value decreases
30% by the excitation of DC current. (reference ambient
temperature 125°C)
・ Temperature rise current : The temperature rises 20°C by
excitation of DC current. (reference ambient temperature 20°C)
